Alexis, Nick, and Ruby come from very different backgrounds: Alexis has spent her life covering for her mom's mental illness; Nick's bravado hides his fear of not being good enough; and Ruby just wants to pursue her eccentric interests in a world that doesn't understand her. The three teens meet when they join Portland County's Search and Rescue. On their first mission, they are teamed up to locate an autistic man lost in the woods. What they discover instead is a dead girl. In a friendship that will be forged in danger, fear, and courage, the three work together to find the girl's killer-before one of their own becomes another victim.
